PATENT FRANK BURLINGHAM, OF MOGRAW'VILLE, NEW YORK, ASSIGNOR OF ONE-HALF TO CLAYTON T. PHILLIPS, OF SAME PLACE.

SLEIGH.

SPECIFICATION forming part of Letters Patent No. 391,578, dated October23, 1888.

Application filed July 5, 1888. Serial No. 279,031.

.To all whom it may concern.-

Be it known that I, FRANK BURLINGHAM, of MeGrawville, in the county ofCortland, in the State of New York, have invented new and usefulImprovements in Sleighs, of which the following, taken in connectionwith the accompanying drawings, is a full, clear, and exact description.

This invention consists in a novel construction of a sleigh having itsbody supported on a bob under the front portion and on runners rigidlyattached to the body and extending under the rear portion thereof, ashereinafter more fully described, and specifically set forth in theclaims.

In the annexed drawings, Figure is a side view of a sleigh embodying myinvention. Fig. 2 is an inverted plan view of the same. Fig. 3 is a rearend view, and Fig. 4 is a ver tieal transverse section taken in front ofthe king-b0lt.

Similar letters of reference indicate corresponding parts.

A represents the body, which may be of any suitable or desired style orconstruction.

B denotes a bob-sleigh, which is under the front portion of the body andsupports the same. It is connected to the body by a kingbolt, a, pivotedto the bob, and the head of this king-bolt has rigidly attached to it orformed integral with it two trunnions, b 1), pro jecting laterally fromopposite sides thereof and connected with journal-bearings c a, rigidlysecured to the under side of the body. The described connections allowthe bob to turn in a horizontal plane without straining the runners, andalso to rock in a vertical plane parallel with the longitudinal centerof the body, and thus obviate undue jarring of the body when travelingover an uneven road.

In order to relieve the king-bolt from excessive torsional strain, Iemploy a fifth-wheel, the lower plate, d, of which is rigid on the bob,and the upper plate, 01, is firmly attached to the king bolt.

To securely sustain the fifth-wheel, I mount the same on knees e e e e,radiating from the fifth-wheel or from a point central over the tworunners of the bob, as shown in Fig. 2 of (N0 model.)

the drawings, and arched, as best seen in Fig. 4 of the drawings.

The rear portion of the body A is mounted on runners r 1', which arerigidly attached at their forward ends to the body and have their rearends curved upward and preferably thence forward, as illustrated at r inFig. 1 of the drawings. On the top of the said upwardeurved ends of therunners 1" 1" is mounted a cross-bar, f, which may be connected theretoin any suitable manner, so as to cause said cross-bar to tie said endsof the runners to each other, and upon this cross-bar is supported thebody A, which may be either mounted directly thereon, as shown, orconnected therewith by means of suitable hangers or arms similar tothose by which vehiclebodies are hung on spring-bars secured to the topof elliptic springs at the ends of the body. The aforesaid upward-curvedends r of the runners can be made to serve as springs for the support ofthe body, and, in fact, both ends of each runner can be made elastic byforming each runner of a continuous bar of springsteel bent into theshape of the runner, as hereinbefore described. The lower portions ofthe runners r r are braced laterally by arched knees or bars h h,extending across the sleigh and secured at opposite ends to theaforesaid portions of the runners.

When the runners r 1" have their lower portions formed with a continuouscurve, as shown, I elongate the road-bearings of the runners byattaching thereto rearwardly-extended supplemental runners t t, as shownin Fig. 1 of the drawings.

Having described my i nvention,what I claim as new, and desire to secureby Letters Patent, 1s

1. A bob having its knees radiating from a point central over the tworunners, as set forth and shown.

2. A bob having a fifth-wheel supported by knees radiating from saidfifth-wheel, substan tially as described and shown.

The combination of the bob having a fifthwheel supported by kneesradiating from the lower plate of said fifth-wheel, the king-boltsecured to the upper plate of the fifth-wheel,

trunnions projecting from opposite sides of the head of the king-bolt,andjournal-bearings for the trunnions secured to the body, substantiallyas described.

4. A sleigh having its knees arched and radiating from a point centralover the two runners, substantially as described and shown.

5. A sleigh having the front portion of the body mounted on a bob,runners rigidly secured at their forward ends to the body and havingtheir rear ends curved upward and forward, a crossbar mounted 011 saidrear ends of the runners, and the rear end of the body mounted on saidcrossbar, substantially as described and shown.

6. A sleigh having runners each formed of a continuous piece, secured atthe forward end to the body, and the rear end bent upward and forward, acrossbar secured to the top of the rear ends of said runners, the bodysupported on said crossbar, and lateral braces secured'at opposite endsto thelower portions of the two runners, substantially as described andshown.

7. The combination, with the body, of bobs under the front portion ofsaid body, runners having their forward ends rigidly secured to the bodyand their rear ends curved upward and forward, a cross-bar secured tothe top of said rear ends of the runners, the body supported on saidcross-bar, lateral braces sustaining the lower portions of the runners,and supplemental runners extending from the aforesaid runners,substantially as described and shown.

In testimony whereof I have hereunto signed my name, in the presence oftwo witnesses, at Cortland, in the county of Cortland, in the State ofNew York, this 29th day of June, 1888.
